Two major challenges facing African neurosurgery include quality and quantity, in both recourses and personnel. Discrepancy is noted between the two poles, namely, the north and south of the continent and the sub-Saharan area. Although reasonably advanced in the north and south, neurosurgery remains poorly distributed and has multiple deficiencies. ⋯ Insufficient state funding and research facilities aggravate the situation and discourage the few well-trained African neurosurgeons to practice in their homeland. For those who do return home, cultural, social, economical, and political issues hinder their performance and hence the quality of neurosurgery delivered in Africa. Strategies for rectification of these handicaps are presented, including the need for high-standard local training and support from international organizations.

An Evolving Clinical Need: Discordant Oxygenation Measurements of Intubated COVID-19 Patients.
Since the first appearance of the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) earlier this year, clinicians and researchers alike have been faced with dynamic, daily challenges of recognizing, understanding, and treating the coronavirus disease 2019 (COVID-19) due to SARS-CoV-2. Those who are moderately to severely ill with COVID-19 are likely to develop acute hypoxemic respiratory failure and require administration of supplemental oxygen. Assessing the need to initiate or titrate oxygen therapy is largely dependent on evaluating the patient's existing blood oxygenation status, either by direct arterial blood sampling or by transcutaneous arterial oxygen saturation monitoring, also referred to as pulse oximetry. ⋯ As such, technology similar to pulse oximetry which can be applied to a patients finger, and then continuously monitored from outside the room is essential in preventing a particularly dangerous situation of unrealized hypoxia in this critically-ill patient population. Additionally, it would appear that conventional two-wavelength pulse oximetry may not accurately predict the arterial oxygen content of blood in these patients. This discordance of oxygenation measurements poses a critical concern in the evaluation and management of the acute hypoxemic respiratory failure seen in patients with COVID-19.
